Scapular glenoid bone grafting device under minimally invasive condition

Abstract

The invention provides a scapular glenoid bone grafting device under a minimally invasive condition. The device comprises a sleeve, a threading rod and a handle, wherein the sleeve is provided with achannel; the threading rod is movably inserted into the channel in a penetrating mode; the sleeve is detachably connected with the handle; a first wedge-shaped face is arranged at one end of the sleeve; a thin groove and a wide groove are formed in the side wall of the threading rod; and a second wedge-shaped face is arranged at the end, close to a bone grafting block, of the threading rod. A method for the device comprises the following steps of S1, driving an anchor into a corresponding area under an arthroscope; S2, enabling the sleeve to be contacted and matched with the bone grafting area; S3, placing the bone grafting block into the sleeve; S4, pushing the bone grafting block into the bone grafting area; S5, fixing the bone grafting block; and S6, after the bone grafting block is fixed, removing a Kirschner wire, and suturing a wound. The bone grafting device is high in threading efficiency, high in positioning precision and capable of effectively avoiding slippage, rotation anddisplacement of the bone grafting block in the bone grafting process and reducing the damage to blood vessels, nerves and other tissues of shoulder joints due to the bad phenomenon of the bone grafting block in the bone grafting process.

Description

technical field [0001] The invention belongs to the technical field of shoulder joint bone grafting, in particular to a glenoid bone grafting device under minimally invasive conditions. Background technique [0002] At present, shoulder dislocation with severe bone defect is a common joint injury in orthopedics and sports medicine. Improper treatment often evolves into recurrent shoulder dislocation and causes severe glenoid defect, which usually requires bone grafting. Conventional open surgery uses an incision method, which causes large trauma and bleeding, and is easy to damage the axillary nerve, musculocutaneous nerve in front of the glenoid, and the suprascapular nerve in the rear; while bone grafting under arthroscopic features is minimally invasive, which can reduce surgical wounds , and damage to nerves and soft tissues. [0003] At present, the main problems of bone grafting devices in minimally invasive surgery are that they cannot provide enough space for bone g...

AI Technical Summary

Problems solved by technology

[0003] At present, the main problems of bone grafting devices in minimally invasive surgery are that they cannot provide enough space for bone grafting, the threading process is complicated, it is inconvenient to push the bone block into the bone grafting area, and the threading wire in the bone block is easy to be entangled, and the bone block from Pushing out of the tube cannot control the rotation and displacement of the bone block, and cannot be effectively fixed after being pushed in place, etc.
